Hex Value "0A" used in PDF417 issue

Avatar

Level 1

I have created a form that produces a PDF417 barcode based on the user input of various fields.  My problem is the requirement of the barcode is that each field is "separated" by hex 0A.  I thought I could just concatenate a string like textfield.rawValue+ "/u000A"+..... would do the trick BUT the resulting barcode ALWAYS has hex 0D instead of hex 0A.  There is a blog by John Brinkman regarding how the xml processor treats line breaks  (http://blogs.adobe.com/formfeed/2009/01/paragraph_breaks_in_plain_text.html) but this doesn't solve my issue.  I'm hoping someone else has run into this issue and can assist.

Thanks in advance!
